Anthracene and its derivatives have been studied extensively in the fields of photochemistry. Photodimerization of anthracene is one of the oldest known photochemical reactions and a classical example of photocycloaddition. Since the fluorescence properties of an anthracene-type monomer and its dimer are different from each other, if the dimer returns to its monomer by mechanical cleavage upon cracking, the dimer structure is applicable as a crack sensor. A novel anthracene-type monomer, AHME, was synthesized and polymerized. The photocrosslinking of polyAHME was investigated by UV-vis spectroscopy, photoluminescence spectroscopy and 1H NMR. The crosslinking of polyAHME were confirmed by 1H NMR. Fluorescence microscopic images of microcracks in the polymeric material were obtained. In this work it was demonstrated that an anthracene based polymer could be used as a crack sensor. |
